Stair-carpet fastener.



JOHN s. JARDINE, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO EDWARD 0. BAYLES, or ABERDEEN, MARYLAND.

STAlR-CARPET FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 657,270, dated September 4, 1900.

Application filed JunelQ. 1899. Serial No. 721,153. (No model.)

To aZZ whom it 772mg concern:

Be it known that I, JOHN S. JARDINE, a citizen of the United States, residing at Philadelphia,-in the county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Stair-Carpet Fasteners, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to stair carpet fasteners, and has for one object to improve the specific features of construction of stair-carpet fasteners, particularly as regards the pivoting-point of an extensible member comprising the securing device.

A further object of the invention is to provide a structure which can be readily formed from a blank of sheet material and will thereby greatly economize the construction and render stronger and more efficient the structure of the fastener.

Other objects and advantages of the invention will hereinafter appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective illustrating the application of the fastener. Fig. 2 is an elevation thereof before the fastener is forced into position. Fig. 3 is a perspective of the fastener. Fig. 4 is a detail perspective of the extensible member, and Fig. 5 is a similar view of an attachment for holding a crash covering.

Like letters of reference indicate like parts throughout the several figures of the drawing.

The letter A designates a channel-bar having side walls A disposed at an angle to the main face of the bar. This bar may be formed of any desired material and, if desired, from a blank of sheet metal. One end of the bar is provided with a securing pin or projection A, while the side walls A are each formed with a series of adjusting-slots A extending inward from the edges and formed with an enlarged recess A' at the base of the adjusting-slots. The extension-bar B is of similar conformation to the bar A, although of such diameter that the walls B of the extension-bar will pass within the walls A of the bar A. This extension-bar is also provided with a securing pin or point B and at its 0pposite ends with outwardly-bent pivotinglugs B of such dimensions as to pass through the slots A and turn within the enlarged recess A of the bar A.

The fastener is assembled with its members at an angle to each other, as shown in Fig. 2, and the barA is then pressed inward to bring both bars into the same vertical plane, thereby forcing the points A and B into the wood of the staircase and firmly securing the parts in position to retain the carpet, as shown in Fig. 1.

It will be seen that this fastener is composed of only two parts, each of which may be formed from a single blank of material, and can thus be very quickly and economically constructed.

The pins or points at one end of each bar have been shown as attached thereto by suit able rivets; but it is obvious that these may be formed from the material ofthe bar when such material is of sufficient strength for the purpose.

When it is desired to retain upon or over the carpet a strip of crash or other suitable protecting-covering, the same may be eifected by means of the attachment illustrated in Fig. 5. This consists, essentially, of arod or wire 0, having at opposite ends eyes or loops 0, through which the. points or pins from the bars are passed and the rod or wire stretched so as to retain a covering in proper position.

It is obvious that changes may be made in the details of construction, configuration, and ornamentation of the fastener without departing from the spirit of the invention as defined by the appended claims.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A channel-bar having pivoting-recesses in its parallel side walls and provided with a securing-pointat one end, and an extensionbar provided with pivoting-lugs engaging said recesses and a securing-point at its free end; substantially as specified.

2. A channel-bar having slots and enlarged recesses in its parallel side walls and pro vided with a securing-point at one end, an

extension-bar lying Within said channel-bar and having outwardly-extendinglugs engaging said reeesses,and a securing-point at the opposite end of said extension-bar; substanof said bar and adapted to lie Within the side walls of the main channel'bar, elongated pivoting-lugs upon one end of said extensionbar and engaging said recesses, and a securing-point at the opposite end of said extension-bar; substantially as specified.

, In testimony whereof I affix my signature in presence of two Witnesses.

JOHN S; JARDINE.
